Abstract

Hydrazinophthalazinones and -pyrido[2,3-d]pyridazinones 3a-j easily underwent a stereoselective condensation reaction with formylferrocene (1a) to give hydrazones 4a-j of E configuration. In much slower conversions acetylferrocene (1b) only condensed with hydrazinophthalazinones 3b,c yielding hydrazones 5b as a mixture of E/Z isomers and 5c purely in E form, respectively. The stereostructure of products was proved by IR, 1D- and 2D-NMR methods and for 4b,j by X-ray analysis.
